Zwicker tones are faint tonal afterimages arising from notched noise

Evidence

A ZT is a faint, decaying tonal percept that can arise following the presentation of a notched broadband noise and that can last up to 5–6 s. The pitch is always within the frequency range of the notch, and depends on the level of the noise and the width of the notch. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5399
